Of course you'd be able to have outdoor Independence Day fun in Hawai'i, even if the celebratory day were in March. You'd be able to picnic on poi, pineapple, and pomegranate, just like any other day of the year. I didn't say "all states", I said "most states". "Most states" is not Hawai'i. "Most states" is Michigan and Indiana. "Most states" is defined as "where houses have root cellars to keep their turnips from turning, their swedes from sweating, and their radishes from rotting."
